They seem easy now because of the changes to classes and all the added abilities. But back in the day when you need a shammy in your group to benefit from hero, few classes had interrupts, DPS couldnt just pew pew pew without pulling aggro (aggro management was a personal responsibility), HEALERS could pull aggro, and you needed to farm resist gear etc etc... I wouldn't say things were harder then, raiding was just different. And yeah -- I raided then too, and I cleared Sunwell before the patch... It wasn't harder, it wasn't easier... it was different.
